Radix

[celoz0828]

I have to implement a function for Radix:

  static void radix(Elem *arr, unsigned int n); // when using radix, Comp should be a class
  // with a static method "uintVal(...)" that gives an unsigned int representation of the item 

I know how to code Radix, just unsure of how to create the uintVal method because I don't understand its purpose. What does that return?
